Modeling and simulation of enhancing nitrification in wastewater treatment though bio-augment

Though bio-augment to enhancing nitrification in domestic sewage Treatment, we build a model by adding a new item in matrix and construct a new equation into equation set. The simulation result show that bio-augment is an effective way to enhancing nitrification. Augmenting quality can improve effect of nitrification. It also can increase nitrifiers Performance and shorten sludge age, therefore, the bio-augment not only can enhance nitrification, but also can enhance phosphorous removal.
